| What it is | 작약 (jakyak), peony root, is one of the four herbs in the classic 사물탕 (samultang) tonic that Korean luxury brands quote constantly. It brings antioxidant and comforting compounds, and it earns its place in soothing formulas — though as with most hanbang botanicals, the lineage is far better documented than the clinical effect. | Marketed relentlessly as a natural BHA. It is not one. Willow bark contains salicin, which is a chemical relative of salicylic acid, not the same molecule, and skin does not convert it into working BHA in any quantity that matters. A pleasant, mild botanical. If you want exfoliation, buy actual salicylic acid. |
